Description

Reported by Kefu Chai:

C_DiscardRequest objects were never deleted because their complete() method was never called. The on_write_persist callback in setup_log_operations() called complete_user_request() to invoke the user's callback, but didn't call complete() on the request itself to trigger self-deletion via Context::complete().
